Replaces the two hardcoded glazing defaults (g⊥=0.63, FF=0.7) in the
cert→inputs mapper with spec-driven lookups:
- g_perpendicular by glazing_type (Table 6b):
single → 0.85, double 2002+ → 0.72, low-E soft → 0.63,
secondary → 0.76, triple → 0.68. Default 0.72 when missing.
- frame_factor by frame_material (Table 6c):
wood/PVC/composite → 0.70, aluminium/steel/metal → 0.83.
Measured values from window_transmission_details / SapWindow.frame_factor
still take precedence. Overshading factor stays at 0.77 ("average") since
RdSAP 10 doesn't lodge a per-window overshading code.
100-cert parity probe:
MAE 5.65 → 5.70 (flat)
exact-match within ±1: 18% → 20%
bias +1.13 → +1.50
Slight bias drift toward over-prediction is expected — bigger solar
gains reduce predicted heating demand. Net: the engine is now more
spec-correct (more exact matches), but composition of errors elsewhere
needs the next slice to bring bias back toward 0.

domna-domain
Shared domain types — Property, Properties, BaselinePerformance, Plan, PlanPhase, Scenario, ScenarioPhase, ScenarioSnapshot, Recommendation, OptimisedPackage, EpcPropertyData, etc.
Boundary: types only. No persistence, no IO, no business logic. Other packages and services depend on domna-domain; this package depends on nothing internal.
Domain definitions live in ../../CONTEXT.md. New types added here must match the glossary terms.
